Title: Cmos type mask rom
Inventor: NAKAMURA TSUNEO
IPC: G11C17/18
Filed: 1981-01-22
Abstract: PURPOSE:To obtain an easily manufactured mask ROM through which no standby current flows, by using desired enhancement and depletion type transistors (TR) in combination as parallel and series P and N type TRs of a decoder for selecting memory chips of N type TRs. CONSTITUTION:A decoding circuit for an N type TR memory chip selecting signal CS consists of series P type TRs 207-210 between a power source and selection lines and parallel-corrected N type TRs 211-214, etc., between the selection lines and earth, and the corresponding TRs 207-210, and 211-214 are driven by external chip selection signals CS10 and CS20 and signals CS10 and CS20 passed through inverters 203 and 204. When boron, etc., is injected into the gates of the TRs 207-214 to increase threshold voltages, enhancement and depletion type TRs are combined in accordance with a mask and since gates, etc., are not used, the need for a standby current is eliminated, thereby obtaining an easily-manufacture mask ROM which has low power consumption and simple constitution.

Title: Silver halide photographic sensitive material
Inventor: MIYAMOTO HAJIME
IPC: G03C1/85
Filed: 1994-01-26
Abstract: PURPOSE:To obtain the photosensitive material high in scratch resistance and adhesion by forming on a support a protective coating layer obtained by curing a composition consisting of a radiation curing resin and an isocyanate type compound by irradiation with radiation. CONSTITUTION:The polyester support is coated with the composition comprising the radiation curing resin and the isocyanate type compound and irradiating it with the radiation to form the protective coating layer.

Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized reading lens in which various aberrations such as a color aberration at first are satisfactorily corrected in a spite of a large aperture of about F3 and having a high resolution by including at least one refractive index distributed lens satisfying specified conditions. SOLUTION: This lens is composed of three groups and three lenses of a first lens G1 consisting of the first group of positive power, a second lens G2 consisting of the second group of negative power and a third lens G3 consisting of the third group of positive power in order from the side of magnification. Then, at least one refractive index distributed lens GRIN satisfying the condition of |ϕs|<|ϕm| is included. Provided that, ϕs shows the power of the form of the refractive index distributed lens and ϕm shows the power of the medium of the refractive index distributed lens.  Since the satisfactory aberration correction is realized by an aberration correction effect of which this refractive index distributed lens GRIN has, large aperture expansion and miniaturization can be achieved by about a half of the conventional number of constitutive lenses.

Title: Digitizer and position determining method therefor
Inventor: MATSUSHIMA KEIICHI
IPC: G06F3/033
Filed: 1995-01-20
Abstract: PURPOSE: To secure a specific position detection precision even when a position signal greatly deviates from a quadratic function and to shorten the time of arithmetic processing therefor. CONSTITUTION: Two adjacent loop coils are selected from a loop coil group arranged on the tablet 1, the 'sum' of and the 'difference' between generated signals through the mutual operation between the selected loop coil couple and the coil L of a position indicator 2 are calculated, and the indicated position on the table of the position indicator is determined from the calculated 'sum' of and the "difference" between the generated signals. Further, when a loop coil couple is selected as an oscillation system which generates the mutual operation and the 'sum' output of an adder 161 indicates a maximum value, the 'difference' output of a subtracter 162 is acquired. Consequently, precise position detection can be performed and the detection processing time can be shortened.

Title: Apparatus for determining catalyst activity for internal combustion engine
Inventor: UCHIKAWA AKIRA
IPC: B01D53/86
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To determine the activity of catalyst in a high precision and indirect manner without detecting the catalyst temperature. SOLUTION: The heat balance of a catalyst is calculated (S11-S13) based on the engine load Tp and the engine revolution speed Ne. If the resulting heat balance is over a positive prescribed value (S14), an activity is determined by using an oxygen sensor provided in the downstream of the catalyst. More specifically, during feedback control of air-fuel ratio (S16) by using the oxygen sensor in the upstream of the catalyst and the one in the downstream of the catalyst, the changing speed of the output from the downstream oxygen sensor is determined whether or not to be a prescribed value (S17, S18). If the changing speed is below a prescribed value, the catalyst is determined to be active (S20), and if the resulting heat balance is below a prescribed value or if the changing speed is over a prescribed value, the catalyst is determined not to be active (S19).

Abstract: PURPOSE:To obtain a compact reproduction head assembly by adhering again a printed base board containing a head amplifier onto a head base which fixes a head chip and connecting the booth ends of a winding wound round the head chip directly to a reproduction head amplifier input terminal. CONSTITUTION:A head chip 1 is attached at the tip of a head base 2 and the booth ends of a winding 4 wound round the chip 1 are connected to an input terminal 6 of a reproduction head amplifier 5 of a printed base board 3 which is adhered at the back part of the base 2. The amplifier 5 consists of a single IC and uses a low-noise bipolar transistor for superhigh frequencies which is connected differentially. As a result, the effective length of the winding 4 is reduced together with reduction the capacity element produced at the input of the amplifier 5, a high band and a high S/N. Thus it is not needed to set the base board of the amplifier 5 into a rotary drum since the amplifier 5 is incorporated into a reproduction head assembly. In such constitution, a compact magnetic recording/reproducing device is obtained.

Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To provide a scanning type probe microscope capable of simply discriminating the optimum frequency for exciting a probe within a short time to measure the surface data of a sample with high sensitivity. SOLUTION: After the initial frequency characteristics of a probe excited in the state not brought into contact with a sample and the reference frequency characteristics of the probe excited in the state brought into contact with the sample are detected, the difference between the initial frequency characteristics and the reference frequency characteristics is operated to calculate the exciting frequency for exciting the probe. As a result, a resonance peak A reduced in amplitude in depencence on the distance between the probe and the sample remains and a resonance peak B not changed in amplitude even if the probe comes into contact with the sample disappears. The remaining resonance peak A is selected and the probe is excited by the frequency of the resonance peak A to perform the AC mode measurement to the sample.
